Working in Ruislip
We cover every part of Ruislip, including HA4, HA5 and UB10, and nearby Northolt (2.9 miles) and Uxbridge (3 miles).
London homes in Ruislip often mean stairs, permits and neighbours below; we plan the logistics as carefully as the bathroom. Where your Ruislip home already has a WC on gravity drainage, a macerator opens up more places a new cloakroom can go. We survey cloakrooms in Ruislip with the headroom in mind as well as the floor area, because under-stair spaces lose height quickly.
Supplies across most of Greater London are very hard. Taps, plug wastes and toilet pans scale up quickly, so chrome copes better than matt black, and a removable aerator is worth having. Hardness varies street by street, so check the figure for your postcode with your water supplier.
What the job includes
- A concealed cistern frame or WC unit where the space allows
- Splashback or feature tiling and a new floor, often LVT or porcelain
- A new waste connection to the soil stack or drain, or a macerator where the rules allow it
- Compact sanitaryware: a short-projection, back-to-wall or wall-hung WC and a corner, wall-hung or slim vanity basin
Decisions to make first
Under-stair layout
Headroom drops quickly under stairs. The basin and the space in front of the WC need standing height; the low end of the room can take the cistern or storage.
Door
An outward-opening door is usually needed so it does not hit the WC. A sliding door suits a narrow hallway where an outward door would block the way.
Rules that apply in England
In England, a new WC connected to the soil stack or drain is drainage work under Part H, and a newly formed cloakroom without an opening window should have mechanical extract; Approved Document F gives 6 litres per second as the design rate for a WC, against 15 for a bathroom. Because a cloakroom has no bath or shower, adding a light to an existing circuit is not notifiable under Part P, but a new circuit is.
